End of the line: proteolytic degradation of cyclin-dependent kinase inhibitors
AbstractCyclin-dependent kinase inhibitors (CKIs) are crucial regulators of cell-cycle progression. The CKI Sic1 controls the timing of DNA replication by inhibiting Clb-Cdc28 kinase. Phosphorylation of Sic1t by Cln-Cdc28 kinase alleviates this inhibition by targeting Sic1 for degradation through the ubiquitin-mediated proteolytic pathway
Constructing accounts of organisational failure: Policy, power and concealment
An example of contracting arrangements within the National Health Service (NHS) provides the focus for considering accounts of organisational behaviour and failure. Public accounts of the outcome are contrasted with information disclosed in response to Freedom of Information Act (FOIA) requests. While the former focused on shortcomings in commercial expertise, sometimes at lower levels within organisational hierarchies, the latter suggests a need to consider the environment of social networks and power relationships. The data suggests obstacles to information flows across organisational boundaries were a contributory cause of failure, but a desire to present the implementation of policy in a positive light encouraged subsequent concealment of what Goffman (1959/1990) described as âdark secretsâ. Through this example, the article provides an exploratory use of FOIA to examine social processes that frequently elude investigation. </jats:p
Evidence-based health policymaking in Iraqi Kurdistan: Facilitators and barriers from the perspectives of policymakers and advisors
From Programme Theory to Logic Models for Multispecialty Community Providers: A Realist Evidence Synthesis
Background:
The NHS policy of constructing multispecialty community providers (MCPs) rests on a complex set of assumptions about how health systems can replace hospital use with enhanced primary care for people with complex, chronic or multiple health problems, while contributing savings to health-care budgets.
Objectives:
To use policy-makersâ assumptions to elicit an initial programme theory (IPT) of how MCPs can achieve their outcomes and to compare this with published secondary evidence and revise the programme theory accordingly.
Design:
Realist synthesis with a three-stage method: (1) for policy documents, elicit the IPT underlying the MCP policy, (2) review and synthesise secondary evidence relevant to those assumptions and (3) compare the programme theory with the secondary evidence and, when necessary, reformulate the programme theory in a more evidence-based way.
Data sources:
Systematic searches and data extraction using (1) the Health Management Information Consortium (HMIC) database for policy statements and (2) topically appropriate databases, including MEDLINE, MEDLINE In-Process & Other Non-Indexed Citations, PsycINFO, the Cumulative Index to Nursing and Allied Health Literature (CINAHL) and Applied Social Sciences Index and Abstracts (ASSIA). A total of 1319 titles and abstracts were reviewed in two rounds and 116 were selected for full-text data extraction. We extracted data using a formal data extraction tool and synthesised them using a framework reflecting the main policy assumptions.
Results:
The IPT of MCPs contained 28 interconnected contextâmechanismâoutcome relationships. Few policy statements specified what contexts the policy mechanisms required. We found strong evidence supporting the IPT assumptions concerning organisational culture, interorganisational network management, multidisciplinary teams (MDTs), the uses and effects of health information technology (HIT) in MCP-like settings, planned referral networks, care planning for individual patients and the diversion of patients from inpatient to primary care. The evidence was weaker, or mixed (supporting some of the constituent assumptions but not others), concerning voluntary sector involvement, the effects of preventative care on hospital admissions and patient experience, planned referral networks and demand management systems. The evidence about the effects of referral reductions on costs was equivocal. We found no studies confirming that the development of preventative care would reduce demands on inpatient services. The IPT had overlooked certain mechanisms relevant to MCPs, mostly concerning MDTs and the uses of HITs.
Limitations:
The studies reviewed were limited to Organisation for Economic Co-operation and Development countries and, because of the large amount of published material, the period 2014â16, assuming that later studies, especially systematic reviews, already include important earlier findings. No empirical studies of MCPs yet existed.
Conclusions:
Multidisciplinary teams are a central mechanism by which MCPs (and equivalent networks and organisations) work, provided that the teams include the relevant professions (hence, organisations) and, for care planning, individual patients. Further primary research would be required to test elements of the revised logic model, in particular about (1) how MDTs and enhanced general practice compare and interact, or can be combined, in managing referral networks and (2) under what circumstances diverting patients from in-patient to primary care reduces NHS costs and improves the quality of patient experience
From programme theory to logic models for multispecialty community providers: a realist evidence synthesis
This is the final version. Available from the publisher via the DOI in this record.Background: The NHS policy of constructing multispecialty community providers (MCPs) rests on a complex

The practice of commissioning healthcare from a private provider: learning from an in-depth case study
Background: The direction of health service policy in England is for more diversification in the design, commissioning and provision of health care services. The case study which is the subject of this paper was selected specifically because of the partnering with a private sector organisation to manage whole system redesign of primary care and to support the commissioning of services for people with long term conditions at risk of unplanned hospital admissions and associated service provision activities. The case study forms part of a larger Department of Health funded project on the practice of commissioning which aims to find the best means of achieving a balance between monitoring and control on the one hand, and flexibility and innovation on the other, and to find out what modes of commissioning are most effective in different circumstances and for different services. Methods: A single case study method was adopted to explore multiple perspectives of the complexities and uniqueness of a public-private partnership referred to as the âLivewell projectâ. 10 single depth interviews were carried out with key informants across the GP practices, the PCT and the private provider involved in the initiative. Results: The main themes arising from single depth interviews with the case study participants include a particular understanding about the concept of commissioning in the context of primary care, ambitions for primary care redesign, the importance of key roles and strong relationships, issues around the adoption and spread of innovation, and the impact of the current changes to commissioning arrangements. The findings identified a close and high trust relationship between GPs (the commissioners) and the private commissioning support and provider firm. The antecedents to the contract for the project being signed indicated the importance of leveraging external contacts and influence (resource dependency theory). Conclusions: The study has surfaced issues around innovation adoption in the healthcare context. The case identifies ânegotiated orderâ, managerial performance of providers and disciplinary control as three media of power used in combination by commissioners. The case lends support for stewardship and resource dependency governance theories as explanations of the underpinning conditions for effective commissioning in certain circumstances within a quasi marketised healthcare system
Performance of Anal Cytology Compared With High-Resolution Anoscopy and Histology in Women With Lower Anogenital Tract Neoplasia
Background: Information on the performance of anal cytology in women who are high-risk for human papillomavirus-related lesions and the factors that might influence it are largely lacking. Aims: Evaluate the performance of anal cytology in women with lower anogenital tract neoplasia. Methods: retrospective study including all new referrals of women with a previous history of anogenital neoplasia, from January 2012 to July 2017, with concomitant anal cytology and high-resolution anoscopy with or without biopsies. Results: 636 anal cytology samples and 323 biopsies were obtained from 278 women. Overall sensitivity and specificity of 'any abnormality' on anal cytology to predict 'any abnormality' in histology was 47% (95% CI 41-54%) and 84% (95% CI 73-91%), respectively. For detecting high-grade squamous intraepithelial lesions (HSIL)/cancer, sensitivity was 71% (95% CI 61-79%) and specificity was 73% (95% CI 66-79%). There was a poor concordance between cytological and histological grades (Îș=0.147). Cytology had a higher sensitivity to predict HSIL/cancer in immunosuppressed vs. non-immunosuppressed patients (92% vs. 60%, P=0.002). The sensitivity for HSIL detection was higher when two or more quadrants were affected in comparison with only one (86% vs. 57%, P=0.006). A previous history of vulvar HSIL/cancer (OR 1.71, 1.08-2.73; P=0.023), immunosuppression (OR 1.88, 1.17-3.03; P=0.009) and concomitant genital HSIL/cancer (OR 2.51, 1.47-4.29; P=0.001) were risk factors for abnormal cytology. Conclusions: Patient characteristics can influence the performance of anal cytology in women. The sensitivity for detecting anal HSIL/cancer was higher in those immunosuppressed and with more extensive disease
